WINDOW-REFRIGERATOR.

Specification of Letters Patent.

Patented Nov. 6, 1917.

Application filed November 19, 1913. Serial No. 801,952.

To all whom it may concern:

Be it known that I, FRANCIS G. Hm, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented a new and useful Window-Refrigerator, of which the following is a specification.

This invention relates to refrigerators, and it consists of a receptacle having its walls separably engaged or interlocked whereby the receptacle may be taken apart when not in use.

An object of the invention is to produce a receptacle comprising inclosing walls provided with means whereby the walls may be interlocked at will to assemble the receptacle, or detached in order to enable the receptacle to be disassembled.

Another object is to provide a receptacle adapted to be positioned within a window or wall opening, and provided with means for supporting articles therein, and with means for supporting the receptacle within the window or opening where it is positioned. 1

Another object is to provide a receptacle adapted to be employed to serve the purpose of a refrigerator in windows or wall openings, and composed of metallic walls provided with detachable interlocking devices so that the refrigerator may be readily detached and disassembled when not in use.

1 Other objects will appear from the following description, reference being made to the accompanying drawings in which I have illustrated a preferred embodiment of my present invention, and in which 7 Figure l is a plan View of the refrigerator supported within awwindow frame, outside of the window.

Fig. 1 is a brokensectional view, showing a corner connection of the end and side walls.

Fig. 2 is a view looking into the refrigerator from within the room or apartment from which the refrigerator extends, the

' window being partially raised to permit access to the contents of the refrigerator.

Fig. 3 is a sectional view on the line 33, for instance, of Fig. 2 looking in the direction indicated by the arrow.

Fig. 4 is a detailed view of the binding or locking device whereby the top or cover of the refrigerator is fastened to or interlocked with the walls.

Fig. 5 is a cross sectional view showing the interlocked connection between the top and the walls of the refrigerator.

Fig. 6 is a detail sectional view illustrating a portion of one of the shelf supports within the refrigerator, and the shelf in position thereon.

Fig. 7 is a view of the supporting blocks or devices adapted to be positioned within the window frame or opening to support the refrigerator therein. I

Fig. 8 is a sectional view on the line 8-8 .of Fig. 7. I

The side wall 1 and the end walls 2 are preferably of sheet metal of'any required quality, and may be of. any desired size. .The outer or rear edges of the end walls are bent to provide inwardly extending grooves or channels 3, the walls of the grooves or channels being integral with the end walls. The ends of the side wall 1 are doubled outwardly to provide engaging projections at which are adapted and arranged to pass into the channels 3 and thereby form an interlocking connection between the side and end walls. The side and end walls may be detached or separated from each other by raising the side wall, which operation slides the engaging projections 4 upwardly within the channels 3 until the parts are disengaged. The upper edges of the end walls are bent to provide depending flanges 5, and the upper edge of the side wall 1 is bent to provide a similar depending flange 6. The top or cover 7, which is also preferably, though not essentially, of sheet metal, is arranged to rest upon the upper edges of the end Walls, and to extend over and beyond the upper edge of the side wall, substantially in themanner shown in Fig. 3. The edge of the top or cover 7 which is above the side wall 1 is bent to provide a groove or channel 8 which is arranged to receive the depending flange 6, in the manner shown in Fig. 3. The bent portion of the side wall and the top or cover are thus interlocked so that it is impossible to remove the top or cover except by sliding the top or cover longitudinally until the interlocking flanges pass beyond each other. The edges of the top or cover above the end walls 2 are bent upon themselves to provide flanges 9. An angular member 10 fits over the corner formed by the meeting of the top and end walls, and is provided with flanges 11 which engage under the flanges 5 and 9, thereby securely locking the t p 01 CQVBI up n the compartment or in closure formed by the side wall 1 and the end walls 2.

The bottom or floor 12 of the refrigerator is preferably, though not necessarily, of sheet metal and rests upon supporting flanges 13 rigid with the inner sides of the end walls. The outer edge of the floor or bottom is provided with a depending flange 1 1, which engages within a grooveorch annel formed by an upturned flange 15 at the lower edge of the side wall 1. Locking devices 16 piv otally supported by the inner side of the side wall 1 engage against the floor or bot tom 12, thereby firmly holding the floor or bottom seated upon the supportingfianges 13, and in interlocked engagement with side wall 1. This prevents thebottom' or floor from being raised, and prevents access to the contents of the refrigerator except through the open inner side,'which becomes obvious by reference to Fig. 3. The'inner edge of the floor or bottom 12 is provided with a depending flange 17, which is straight or flush with the inner vertical edges'of the end walls 2.

The end walls may be provided with parallel supporting flanges 18, at a suitable distance from the top and bottom, and'a shelf 19 may be mounted upon said supporting flanges. The inner and outer "edges of the shelf 19 may be'provided with depending flanges 20 extendingdownward'ly at opposite ends of the supporting'fianges 18 to prevent movement of the shelf and to hold the shelf securely in position.

As previously mentioned the refrigerator is particularly adapted to be supported within a window or opening, outside of the window, for instance. lNhen so used the lower edges of the end walls may rest upon the lower part of the window frame, as shownin Fig. 3. The inner edges of the end walls are provided with outwardly extending'reinforced flanges 21 arranged to engage against the inner sides of retaining strips 22 fastened within the window frame; The lower sash of the window frame operates close to the inner edges of the end walls, and upward movement of the refrigerator may be prevented by any suitable device or expedient, such, for instance, as screws or bolts 23 passing through the end walls and into the retaining blocks. Access to the screws or bolts 23 is impossible from the'eX- terior, and they may only be reached by raising the window and from the'inside.

The inner edge of the top or cover 7 is provided with a portion 24 which extends obliquely upwardly and inwardly, and is beaded or rolled at its upper'or inner edge. The beaded or rolled inner edge of the top or cover forms close contact with the window, as shown in Fig. 3, so thatit is impossible to reach the contents of the refrigerator from outside the window. The extended portion 2 1 of the top or cover (1011- stitutes an abutment to prevent the window from moving above the top or cover.

From the foregoing it will be seen that my improved refrigerator is preferably composed entirely of sheet metal, and is perfectly sanitary because all parts are nonabsorbent and are easily kept clean. hen it is desired to position or mount the: refrigerator within the window or opening it isonlynec essary'to secure the retaining blocks or strips 22'tothe window frame and then position tliej refrigerator outside the window, and engage the retaining flanges21 with the retaining strips. The bolts or screws 23 maythen be placed in position to prevent; rembval of thc refrigerator by any oneoutside the window.

The interlocked engagement of the different walls forming the refrigerator prevent foreign substances'from entering the reff'igferatorl In" order to disassemble the refrigerator, after its removz'il from the window, is only necessary to slide thelocking devices downwardly until 'they are disengaged from the flange'son the top and end walls, and then to slide or move the top longitudinally until'it is disengagedfrom the "side wall 1; then to slide or move the side wall and end walls until the interlockingnan ese "and '41 aredisengaged. When therefrigeratoi' is thus disassembled the different parts thereof may be placed fiat upon each other andwill occupy a minimum amount'o'f space, sotha't when the device is not in useit may be conveniently and readilystorecl. v v I To accommodatea refrigerator of asingle size to Windows or openings of different dimensio'n's, it is only necessary to provide more'or less of theretai'ning strips 22, which maybe fastened together, one against the other, in the manner shown in Fig. 8. k 4

1 have shown"and described a preferred embodiment of'my invention, but it is obvious that various alterations and changes may'bema'de in the construction and arrangement of the parts withoutdeparture from the spirit'and scope of the invention. 1 do not restrict myself toidenti'cal features of construction or arrangement except as pointed out in the appended claims.

WhatI claim and desire to secure by Letters Patent of the United States is:

1. A metallic structure including end walls, a si'ngleside wall connecting theend walls, a top'covering the space included between the side and end walls, and a bottom arranged within the side and end walls below the top, the meeting edges of the side and end walls being respectively formed for interlocking connection to secure the parts against othertha'n" a relatively sliding movement, the meeting edges of the top and side wall being formed for an interlocking connection to prevent other than a relative sliding movement of the said parts, the meeting edges of the top and end walls having out-turned similar flanges, and a corner piece slidingly cooperating with and embracing both of said flanges to secure the said edges of the top and end walls in cooperative relation, and means for fixing the bottom with respect to the side wall, outwardly extending flanges formed on the edges of the end walls remote from the side wall.

2. A metallic structure including end walls, a single side wall connecting the end walls, a top covering the space included between the side and end walls, and a bottom arranged within the side and end walls below the top, the meeting edges of the side and end walls being respectively formed for interlocking connection to secure the parts against other than a relatively sliding move- Gopies of this patent may be obtained for ment, the meeting edges of the top and side wall being formed for an interlocking connection to prevent other than a relative sliding movement of the said parts, the meeting edges of the top and end walls having out-turned similar flanges, and a corner piece slidingly cooperating with and embracing both of said flanges to secure the said edges of the top and end walls in cooperative relation, and means for fixing the bottom with respect to the side wall, outwardly extending flanges formed on the edges of the end walls remote from the side wall, and a guard strip extending upwardly from the edge of the top, remote from the side wall.

In witness whereof, I have signed this specification in the presence of two subscribing witnesses.
